I would put 90% of guys (at least) in the category where they talk about sex, they make sex related jokes, they talk about girls in sexual ways, etc. I have this one friend though, a good friend, and he is very nervous about the whole subject. Now, he wants a gf, he wants children (that is what he talks about all the time), but whenever this subject comes up, he is nervous and embarassed to talk about it. So what's the deal? I don't see the big deal.
